When I try to run some games the screen gets offset, with the black edges making a cross type shape on the right side of the screen. It puts the upper right corner of the game in the center, with the bottom right corner above it and the left corners and edges on the far right. This has happened with a couple of online download games i have tried, as well as the cinematic for warcraft 3 and the frozen throne, plus always shows on the blue hp start up screen when the computer is turned on or reset. Anyone seen this and have a solution?

This also happened to me when I installed warcraft 3 on Vista. My friend tells me that it is not compatible and I should run it in compatibility mode but it doesn't really help. It became stable when my OS updated itself, I'm not sure if thats the solution but it is for me.
